Cooking food is something we have done since the first caveman threw a mammoth steak on the fire. While it is true that cooking does cause chemical changes in food and a loss of some nutrients, it is a clear case of being alert and not alarmed. Every time we cook food, there is some degree of nutrient loss. Exposing food to heat, oxygen or light alters the nutrients found in food. It is not all bad news though because cooking food also has its advantages. Cooking food can increase its digestibility, meaning you will get more nutrients out of it. And even though there may be less of some nutrients from cooking, it is swings and roundabouts as the availability of certain phytonutrients increases. And of course, let’s not forget that heating food kills some of the nasty microbes that can cause food poisoning. The principle behind a raw food diet is that cooking food destroys the natural enzymes and nutrients that would otherwise give us optimal health and control body weight. A raw food diet is almost entirely plant-based and includes fruits, vegetables, nuts, seeds, grains, vegetable oils and juices in their natural uncooked state. Now on the pro side for a raw food diet, it means if you are currently eating a lot of processed food, then switching to raw food will be a clear nutritional win. So that gets a big tick. Unquestionably, there are many benefits to eating plenty of fruits and vegetables. These foods are high in nutrients and fibre and low in kilojoules. But is raw superior to cooked? A review of 28 research studies found eaters of both cooked and raw vegetables had a lower risk of cancer compared to people who did not eat many vegetables in the first place. Where the science gets murky is the claim that raw food is better because cooking destroys the enzymes found in plants. It is 100 percent correct that cooking will do this. But so too does digestion. Few enzymes survive their trip through the hydrochloric acid spa bath in the stomach. And those plant enzymes are essential only to the plants. The...

SEOUL, SOUTH KOREA — U.S. President Donald Trump’s decision to withdraw from the Iran nuclear agreement is not expected to derail diplomatic momentum to reach a deal to end North Korea’s nuclear weapons program, but it could complicate the negotiation process, analysts say. Trump on Tuesday announced that the United States is ending its participation in the 2015 Joint Comprehensive Plan of Action (JCPOA) that lifted sanctions on Iran in exchange for Tehran limiting its nuclear program, and would re-impose U.S. economic sanctions on Iran. The agreement was negotiated by the administration of Trump’s predecessor, President Barack Obama, and involved five other world powers; Great Britain, France, Germany, China and Russia. Trump’s National Security Adviser John Bolton said the U.S. decision to re-impose sanctions on Iran will set a higher standard for North Korea nuclear talks by sending, “a very clear signal that the United States will not accept inadequate deals.” The U.S. policy reversal on Iran should not seriously impede diplomatic progress underway with North Korea, said Victor Cha, a noted Korea scholar with the Center for Strategic and International Studies in Washington. “In terms of how the North Koreans would take it, I don’t think they’d take it one way or the other. I don’t think they’d see it as negative or positive because they think they’re different from anybody else anyway. They think they’re a very special case,” Cha said at a CSIS conference this week. While the Iran deal limited that country’s efforts to develop a nuclear bomb, North Korea already possesses 20 to 60 nuclear warheads, according assessments by the U.S. Central Intelligence Agency and the Defense Intelligence Agency, and between 40 to 100 nuclear development facilities, according a report from the RAND Corporation security research organization. But apprehension over whether future U.S. presidents would uphold a nuclear deal reached by Trump could reinforce the North Korean demand for early concessions. John Delury, a North... Question: Why did the US leave the Iran nuclear agreement? === The answer to the above question is
Because the deal was inadequate

Those of you who are regular readers of Beauty Best Friend will know that I suffer from a very sensitive, itchy scalp and I am constantly on the hunt for haircare products that are natural and non-irritating but that also treat my hair well and leave it feeling soft, shiny and clean. So far my experience has generally shown me that natural, SLS-free shampoos and conditioners do not irritate the scalp as much as their chemical filled cousins, but that they do not always clean the hair as well and can leave it looking and feeling greasy, sad and lifeless. One of the first SLS-free shampoo and conditioners that I tried, back in 2013, was Mild Shampoo and Gentle Conditioner from Naked. The relief that I got from my itchy scalp was almost instant, but I did find that it didn’t remove grease and oil from my hair too well, and I had to wash my hair a lot more often. Since then I’ve tried lots of different SLS-free haircare products, all of which have had their benefits and downfalls. For the past month I have been using Rescue Intensive Care Shampoo & Conditioner from Naked, aimed at frizzy, dry and damaged hair. As I had found such relief from my itchy scalp when using Naked products previously I wanted to try out another variant to see if it cleaned my hair any better. Prior to using the Rescue duo I had been having a really hard time with my scalp, but after just the first use of these natural products the itching had subsided about by 75%. Both the shampoo and conditioner have a lovely rich almond scent which stays on the hair after it is dry. The conditioner is a thick, rich cream and it feels like it is giving dry hair a real treat. Unfortunately these Naked products still don’t clean my hair as well as some other products, and I still feel that my hair can look greasy and lank the day after I’ve washed it. I have tried the ‘reverse poo’ method which helps a bit – this means conditioning your hair first, then shampooing it second – but my hair can get very tangled after the shampooing stage.
